3500 lb Drop Axle Guidance

  • Minimum (No Brakes): 14" total (7" overhang per side)
  • Minimum (With Brakes): 14" total (7" overhang per side)
  • Maximum Overhang: 18" total (9" overhang per side)

Example for a 75" Hub Face:

Minimum Spring Center (No Brakes): 75" - 14" = 61" spring center.

Minimum Spring Center (With Brakes): 75" - 14" = 61" spring center.

Maximum Spring Center: 75" - 18" = 57" spring center.

For a 75" hub face, the recommended spring center range is between 57" and 61", depending on whether the axle has brakes.

Overhang Summary

Axle overhang is the distance from the hub face to the spring center.

A shorter overhang (wider spring center) increases axle strength and improves load handling.

A longer overhang (narrower spring center) increases leverage but reduces stability and axle capacity.

Match existing spring centers when possible. This information is for guidance only.

Customer photo review of 3500 lb Trailer Axle With Idler Hubs | Round Drop

I was a little worried at first because some of the reviews mentioned that there was not good customer service response. However, I found customer service to respond very quickly to my emails. The package was delayed by UPS, no fault of traileraxlestore and customer service responded to all my questions quickly and professionally. The axle quality was great. The spring seats were welded to my spec exactly. Can't believe how quickly they were able to complete it as well. Very happy, thank you TrailerAxleStore

Perfect so far…. exactly what I ordered, the only problem I had was I couldn’t track shipment, other than that everything is good, hauled down the road, empty, it did great, haven’t put a load on it yet, but it should be fine.

This was a quick and easy fix I had it replaced in under an hour and have already pulled the trailer from mid Michigan to southern Texaswith no problems whatsoever

This axle changeout was my first. Angelo and The Axle Store was absolutely helpful. Angelo steered me in the right direction on trailer stability, fitting my trailer with a perfect axle. I couldn’t be happier. Thank you!
